| 摘 要： | 【目的】了解国标优质籼稻的米质特点.【方法】以广东省最近育成的水稻品种粤晶丝苗2号等为研究材料,对稻米碾磨品质、外观品质、蒸煮食味品质、营养品质和淀粉RVA谱进行了测定和相关分析.【结果和结论】国标优质籼稻具有整精米率较高、粒型窄长、腹心白少、透明度好、直链淀粉含量适中和长胶稠度等优点;蛋白质含量品种间差异不大,脂肪酸含量品种间的差异较大,粤秀占、巴太香1号、粤晶丝苗2号的脂肪酸含量较高;国标优质籼稻的RVA谱具有高崩解值、低消减值的特点,食味品质优于非国标优质籼稻,其中粤晶丝苗2号的崩解值和消减值符合公认的优质食味指标值,是一个食味品质优良的籼稻品种.直链淀粉、胶稠度与RVA谱的冷胶黏度、崩解值和消减值密切相关,在水稻品质育种中增加RVA谱测定,尤其是将直链淀粉、胶稠度的选择与崩解值、碱消值分析相结合,可有效地提高水稻食味品质选择的准确性.
